To a/VZZ whom it mayv concern:

Be it known that I, OTHO MENDLESOHN OTTE a citizen of the United States, residin at Pittsburg, in the county of Allegheny an vState of Pennsylvania, have invented or discovered certain new and useful Im rovements in Fireprooff` Windows for Bui dings, of which'improvements the following is a specification.

The invention described herein relates to certain improvements in reproof Windows for buildings, and has for its object a construction and combination of parts whereby the sashes move in the openings formed in the wall without the interposition of a guiding and supporting frame.

It is a further'objectof the invention to provide dust and iire proof seals along the edges of the sashes and to so dispose such seals that they 4shall be protected from distortion'and injury either by hard use or by heat; further, to provide for the automatic closing of the sashes whenA the temperature adjacent thereto reaches a dangerous height; nally, in structural features, .all of which are hereinafter more fully described and claimed.

In the accompanying drawings, forming a part of this speciiication, Figure 1 shows in elevation avportion of a wall of a building provided with a windowwhich embodies my irnprovements. Fig. 2 is a section on the line II II, Fig. 1. Fig. 3 is a similar view of the lower portion of the window, the line of sec tion being indicated at III III. Fig. 4 is a horizontal section on the line IV IV, Fig. 1. Fig. 5 is a view, partly in elevation and partly in section, showing in detail the construction of the lower end of the lower sash oi Fig. 1. Fig. 6 is a section in the line VI VI, Fig. 5. Fig. 7 is a view similar to a portion of Fig. 5, showing a structural modification. Fig. 8 is aview similar to Figs. 2 and 3,

illustrating structural modifications. Fig..9 is a horizontal section through the side of the lower sash .of Fig. 8, the line of section being indicated at IX IX. Fig. 10 is a section on the line X X, Fig. 9. Figs. 11 and y12 are sectional views of detailed arts. Fig. 13 isaview in elevation of a win ow-sash from within, showing the'arrangement of exterior braces for the window-panes, the interior braces and the panes being removed. Figs. 1.4 and 15 are sectional views on the lines XIV XIV and XV XV, Fig. 13 ,fand Fig. 16 is a detailed pertendin spective view illustrating a modification in corner construction.

In the several figures structural parts which are repeated bear the same referencenumerals in each case.

In the practice of my invention guidestrips 1 and 2 are embedded firmly in the side walls of the window-opening. It is preferred that` these guidestri s should be properly spaced and tied toget er at their lower ends by means of bolts 3 and sleeves 4, the latter surrounding the bolts between ,the strips.4

They may be spaced and tied at other suitable or desired points throughout their length. It is preferred that the bolts and. sleeves should be embedded in the sill or side walls of the window-opening, as shown. TheL upper ends ofthe strips project through a top p ate 5, resting at its ends on the side walls of the window-opening. The `guides and top plate are adjustably connected by wedges 6, passing through slots in the strips and bearing on op osite sides of the plate.

-The s1 e rails 7, to rail 8, and bottom rail 9 of the sashes are ormed of channel-bars, connected at their corners, by malleable castiron blocks 10, provided with reduced angular extensions 11, fitting into the channelbars and secured thereto by screws or rivets.

A modification in structure is shown in Fig. 16. The side and top rails (formed in this instance of Z-bars 8 and of T-bars 28C) which will be protected from the heat and X flames by the sides of the channels, serve as sealing-strips to prevent the passage of dust, smoke, &c.

In order to prevent edgewise movement of the sash, balls 13 are mounted in the cornerblocks 10 andare yieldingly pressed against the edges of the guide-strips.

A convenient construction for yieldingly holding the sash against edgewise inovement; is shown in Fig. 5 and consists oi rods 14, ex"

transversel throughthe channelbar, w 'ch forms t e bottomfrail 9 of the` IOC IIC

sash, backed by sA rings and abutting against the said balls. n the form shown .in Figs. and 6 two rods extend from either side ap-' proximately to the middle, where they bear i' on opposite ends of a coiled sprin 15.

able longitudinally in rail 9 and secured in place by a clam ing-screw 17, which enga 'es g the block and tlife edges of aslot 18fin rai 9.

view corresponds with the left-hand end 'of Fig. 5. In placelof a single ball a plurality of balls 13EL are employed. .In place 'of rod 1.4

-a rod 14Il is employed, provided at its outer end with a suitable bearing-surface for the balls. Rod 14a is yieldingly mountedv in the sash by means of a spring 15, Which-surrounds the rod and bears at one 'end against I the rear wallof a suitably-formed containingcavity andat the other end upon a suitablydis osed shoulder upon the rod itself.

n Fig. 1 I have shown ina single structure both forms 'of bearing described above. In Fi 11 I have illustrated 'another means of holding the sash against 'edgewise movement between the guide-strips. 4A springplate 32, carried by the sash, en ages strip 1, and the partspare so disposed t at the tension of the spring is exerted to resist any lateral movement of the sash. It will be not-ed of the form 'shown in Fig. 11 that the sprin plate 32 serves not only to hold the sas against movement, but serves also as asealin strip for the purpose already described in connection 'with spring-plates 12 of Fig. 4. The ledge 19 on the sill is formed by an an le whic 'is preferably embedded in the sill and tied to the guide-strips by the bolts 3, as shown.

In order to prevent the entrance of dust above the upper s a'sh, a spring 20 is attached to an an le-bar 21, secured to the top plate 5 in suc manner that the free portion of the' spring will bear ainst the up er sashrail when the sash is iilgos'e'd. A mo ification of. this feature is illustrated in Fig'. 8, Where l the spring 2O"L instead 'of engaging the exteagainst the rail of the lower sas rior of the top rail V0f the sash 1s adapted when the sash is raised to enter the channel which in that form extends across the upper edge ofthe sash Iand to -enga' e 'the inner sur- Y A ermeticjoint is. formed at the meeting-rails ofthe sashes byA face of the channel-wall.

means of Ia spring-plate 22, -secured to the rail of the up er sash and ada tedto bear In order to prevent this spring-plate from being diss spring is carried in a block 16, a just-v torted or destroyed by heat, a back of iiuif asbestos is provided.

A convenient lock consists of a pin 23, arranged to move transversely of the channel forming the upper rail of the lower sash and caused to engage the upper sash by a s ring 24, arranged in the channel-bar ofthe ower sash. The handle of this pin is constructed to permit of the sash-supporting chain 25 being detachably connected thereto. This chain is connected at one end to tov plate 5, the free or Idepending part being adiapted, as stated, to be `connected at any pointv to the pin 23.4 The upper rails of the'sashes are connected by chains 26 assing over pulleys 27 on the top plate, so t at a movement lof one `sash will cause or permit a `corresponding movement of the other sash. The lower sash is made heavier than the upper sash by the placing of suitable weights in the lower rail of the lower sash, so that when free to move the lower sash will drop, raisin the upper sash. In ord-er that the sashes wi close automati'cally in case'of iire, a ortion a of the chain is formed of readily-fusi le material and preferably located near the top of the upper sash, as shown. By forming withinthe arch of the windpw-opening a concrete box `or block-35, as illustrated in Figs. 1 and 2, I am able to Adispose in a convenient manner the pulle s 27 and in so doing to 'employ aiireproo structure.

' As shown in the drawings, the periphery of the sashes is preferably channeled. As shown in Figs'. 2,3, and 4 the rail of the sash is formed of a channel-bar 7 and angle-bars 28 and 29. As shown in Figs. 8, 9, and 10 this rail is formed of a T-bar 7 E and two anglebars 28a and 29a. In Fig.. 11 a Z-bar 7b and two angle-bars 28b and 29b are employed for the same purpose. In Fig. 12 a -Z -bar 7 9 and a T-bar 28c constitute the rails. The last is my preferred construction. In each ease the pane of the sash is held lbetween the o positely-arran ed faces ef the bars which orm therails. film of sbestos is preferably introduced between tne bearing-faces `and the ane.

Figs. 9 and 10 illustrate a modiiication in the bearing between the side rails of the sash and the uide-strips 2. Within the channel IOO lor`

in the e ge of the sash a suitable bearin'gl 'chamber is formed, and within this chamber bea'rin -balls 13b are confined. These balls gages u on one side the inner face of one of the wal s of the channel and upon the other side a bearing-strip 31, yieldingly mounted upon the sash. A strap-s ring 32 anda distance-bolt 33 may be emp oyed for adjusting the position of the strip 31. As already described, strap-spring 32 extends to engage the end of guide-strip 2 lto resist edgewise movement of the sash.

aFig. 12 serves further to illustrate a springsealfor the end of the sash. The strap-spring 34 is arranged to extend' throughout the length of the bottom or top rail It protrudes when the sash is opened beyond the edge of the rail, (and is so .shown in the iigure.) When the Window is closed, however, the spring is compressed into alinement with theedge of the sash and forms a tight contact with the sill. y

In Figs. 13, 14, and 15 means for securing and bracing the Window-panes are shown.

The sash shown is adapted to receive a number of separate panes. On the outer side of the sash extend vertical and horizontal braces 36 and 37. Ordinarily there will be a plurality both of vertical and horizontal braces, and they will form two series. The braces of one series (6; g., the vertical series) are continuous and. straightfrom top rail to bottom rail, and the braces of the other series areinterrupted at the meeting-points. The ends of each brace are secured to the sash itself. A similar arrangement of braces is placed on the innerside, and they too are ordinarily disposed in a series of vertical braces 42 and a series of horizontal braces-43. 'lhe outer vertical braces beingcontinuous and straight, the innerl horizontal braces are `made continuous and straight, and vice versa, and the inner ybraces of the other series instead of ,being interrupted at the meetingpoints are offset at those oints. Thus all the inner braces are integra from one side of the sash to the other, and each is secured to the sash at either end. The outer braces 36 and 37 preferably consist of a body portion, adapted to engage the surface of the pane, and a tongue portion 38 and 39, adapted to lie between the edges of the panes.` These tongue portions may conveniently be prolonged, as at 40 and 41, for securing in the sashes. l f

No claim is made herein to-the construction of Window-sash, as the same forms the sub'ect-matter of another application to bei file in due time.

I claim as my invention- 1.
